calculate BMR

calculate BMR

i dont know how as i wouldn't know how to factor in things like walking, exercise, moving around, etc. And the calculators are all crap, one will say 2200, one will say 3100, one will say 2600.

there should be one where you can rate your activity level

yeah i know, most calculators come out to 2400 or so for BMR. Some say closer to 3000 like the Katch-McArdle Formula.

Either way i dont know if i trust those scales. They don't consider individual MR which can be based on a variety of things. they also ignore muscle mass. Some calculators give me an end reading (after factoring in exercise & lifestyle) of 3700, some give me 3300, some 2800.

but i think 2500 is a good estimate for my BMR.


Anyway, when i was losing weight (up until a few months ago) i was losing 2-3 lbs a week on 2800 calories a day with a moderately sedentary lifestyle (didn't have to walk around for school or do much activity) and about 180 min. of cycling a week.


If 2.5 lbs = 9000 calories/7 = 1285/day deficit on a 2800 cal diet. so my normal metabolism is around 4000 a day?
